Equivalency Evaluation of the U.S. Environmental Protection Agency's Nonroad Diesel Engine Standards
We intend to review the U.S. Environmental Protection Agency's (EPA) standards for nonroad diesel engines to determine if certain EPA requirements in 40 CFR part 89, Control of Emissions From New and In- Use Nonroad Compression-Ignition Engines, provide, or can be modified to provide, at least the same degree of protection as our existing applicable requirements in 30 CFR part 7, subpart EDiesel Engines Intended for Use in Underground Coal Mines. This review is limited to the testing of Category B diesel engines as defined in 30 CFR 7.82, Definitions.
High-Voltage Continuous Mining Machine Standard for Underground Coal Mines
We (the Mine Safety and Health Administration (MSHA)) are reproposing provisions involving two issues included in the notice of proposed rulemaking that was published in the Federal Register on July 16, 2004. These issues involve the following: Types of trailing cables that can be used with high-voltage continuous mining machines; and a requirement to use high-voltage insulating gloves or insulated cable handling tools when handling energized high-voltage trailing cables. In connection with the second issue, we are also addressing the availability requirement for high-voltage insulating gloves and insulated cable handling tools, and the safety requirements for these tools. We are reproposing these provisions after consideration of the oral and written pre- and post-hearing comments that we received.
